Question: Is there a platform that can help me identify key concepts and themes across multiple research papers?

If you want a service to help you find key concepts and themes across a collection of research papers, Elicit is another top contender. This AI research assistant can summarize and extract data from more than 125 million research papers, which is good for empirical subjects like biomedicine and machine learning. It can also spot themes and concepts, which is useful for accelerating literature reviews and automating systematic reviews and meta-analyses.

Another top contender is Semantic Scholar, a free AI-powered research service with a broad database of more than 219 million papers across all scientific fields. Semantic Scholar has powerful search filters, brief summaries and AI-powered research feeds. It also has tools to organize papers into folders, cite papers in different citation styles and suggest papers based on your interests.

Consensus is another service worth a look, with AI insights powered by OpenAI and proprietary large language models through Copilot and Consensus Meter. It covers a wide range of research, has proprietary search tools and filters like study design and methodology. It's good for accelerating literature reviews and getting a quick validation of research.

If you want something more specialized, Epsilon has tools like Investigate for summarized answers with inline citations, Search for organizing publications and patents, Validate for extracting key information from multiple papers, and Synthesize for creating detailed summaries. Epsilon's use of GPT-4 to focus on factual, trustworthy results means it's a good tool for researchers who need results that are authoritative and comprehensive.
